# SARAddBandInterferogram
|
|
|
|
|
|
Replace an amplitude for input interferogram.
|
|
|
|
|
|
## Description
|
|
|
|
|
|
Replace an amplitude for input interferogram and merge it to rebuild three bands (amp, pha and coh).

## Examples
|
|
|
|
|
|
From the command-line:
|
|
|
|
|
|
```
|
|
|
otbcli_SARAddBandInterferogram -ininterfamp interferogram_amp.tiff -ininterf interferogram_phacoh.tiff -out outInterferogram.tiff
|
|
|
```
|
|
|
|
|
|
From Python:
|
|
|
|
|
|
```
|
|
|
import otbApplication
|
|
|
|
|
|
app = otbApplication.Registry.CreateApplication("SARAddBandInterferogram")
|
|
|
|
|
|
app.SetParameterString("ininterfamp", "interferogram_amp.tiff")
|
|
|
app.SetParameterString("ininterf", "interferogram_phacoh.tiff")
|
|
|
app.SetParameterString("out", "outInterferogram.tiff")
|
|
|
|
|
|
app.ExecuteAndWriteOutput()
|
|
|
```
|
